Question

在新安装后尝试使用Mono中的hello world示例。按[http://www.mono-project.com/docs/getting-started/mono-basics/][1]：

的指示尝试了GTK示例

mcs hello.cs -pkg:gtk-sharp-2.0
mono hello.exe

我得到了这个：

知道是什么导致了它吗？

Answer 1

Jonathan Pryor在Xamarin forum中非常好地回答了这个问题。他回答的这些内容帮助了我：

您没有导出$ DYLD_LIBRARY_PATH或$ DYLD_FALLBACK_LIBRARY_PATH以便找到它。

...

问题是无法找到libgtk-quartz-2.0.0.dylib，因为它已安装到/Library/Frameworks/Mono.framework/Libraries，而不是/ usr / lib（或任何全局）。

首先在shell中运行以下内容，然后mono hello.exe应该可以运行：

export DYLD_FALLBACK_LIBRARY_PATH=/Library/Frameworks/Mono.framework/Versions/Current/lib:/lib:/usr/lib

Answer 2

第一条错误消息

＆＃34;类NSView中的userSpaceScaleFactor在10.7及更高版本中被弃用＆＃34;

GTK的用户可以忽略

。但是，在Apple删除引用的调用之前，GTK开发人员社区必须更新其代码。

Apple Dev Community Notices re userSpaceScaleFactor

用于隔离第二个问题的脚本。不要忘记chmod + x它。

#!/bin/zsh
export DYLD_FALLBACK_LIBRARY_PATH=/Library/Frameworks/Mono.framework/Versions/Current/lib:/lib:/usr/lib

mono $1.exe

OSx mono gtk你好世界。 Gtk.Container抛出异常
